HN automatically hides your password when you input it into the comments, like mine is ******, to me it shows up as ******, but to you you see ******.

Does it do this predictively or intuitively somehow? How does it know your password? Is it keeping it as clear text on the client side?

it hashes all the substrings you type to check for collisions.e.g. *****

It probably checks each token's hash for a match. Hold on, trying it now: *****

It is a joke to see who will post their passwords.

So if I type Meatmybeat*123 you just see asterisks ? That nice.

if there was any doubt, what you have written is your username with the year behind it and if that is your password you should change it immediately.
